A round robin was conducted to evaluate the state of the art of room acoustic modeling
software both in the physical and perceptual realms. The test was based on six acoustic …

Simulating sounds produced by realistic vibrating objects is challenging because sound
radiation involves complex diffraction and interreflection effects that are very perceptible and …

To be immersed in a virtual environment, the user must be presented with plausible sensory
input including auditory cues. A virtual (three-dimensional) audio display aims to allow the …

A virtual speaker demonstration system is disclosed that permits a retail outlet to use a
reference speaker to demonstrate the performance of multiple different demonstration …

Room acoustical simulations are usually evaluated by comparing them to measurements in
corresponding physical environments as a benchmark. However, it proved to be challenging …

Determining early specular reflection paths is essential for room acoustics modeling. Beam
tracing algorithms have been used to calculate these paths efficiently, thus allowing …

In order to enable the user of a virtual reality system to be fully immersed in the virtual
environment, the user must be presented with believable sensory input. Although the …

Current linear modal sound models are tightly coupled with their frequency content. Both the
modal vibration of object surfaces and the resulting sound radiation depend on the vibration …
